Nanocatalysts: Revolutionizing Chemical Reactions at the Atomic Level
Nanocatalysts are catalysts with particle sizes in the nanometer range (1-100 nm). Due to their high surface area-to-volume ratio and unique physicochemical properties, nanocatalysts facilitate faster and more selective chemical reactions compared to conventional catalysts. The ability to manipulate catalysts at the atomic scale enhances their reactivity, allowing for more efficient and sustainable industrial processes.
Nanocatalysts have found applications in various sectors, including energy, pharmaceuticals, and petrochemicals. Their ability to improve reaction kinetics while minimizing unwanted byproducts makes them indispensable for modern industrial processes.
